To all whom may concern."

Be it known that I, User-in CHARLES dorm tain new and useful Improvements in 11121110 Bench and Cot Combinations or which the following is a specification.

My invention relates to improvements in piano-bench and cot combinations and the object oi": my improvement is to produce a device that is of collapsible form and that in one position of theparts is adapted to serve as a piano 'b'enchfand in another position thereof is adapted to serve'as a cot, and that, ,:Eurtherniorr-z involves certain details. whereby, the arrangement of the parts for the one use orthe other'is facilitated.

in the accompanying drawing Figure 1 is a sidefelevation of my im proved piano-bench and cot combination in the folded or closed position, as used for a piano-bench, showing the-particular side that serves as the toot board structure with the device in the opened-out position, as used +2 1- a cot? s Figure 2 is an end elevation of the same,

" showing the end wall of the bench that is aiiixed to the head-board and serves as a part of the stringer or side-board structure of the cot that is on the right side.

Figure 3 is plan view of" the same with the cover open. l

Figure 4: 's a plan View with the parts in the open position, for use as a c0t,'soine of the parts being indicated in the partially collapsed position by broken lines. I

Figure 5 is a longitudinal. sectional view on the line 55-95 of Fig. 41-. I

Figure 6 is a, p I an. enlarged scale of: one of the front corners.

Figure 7 is a similar view of: one of the rear corners.

Figure 8 is a fragmentary side view of one oi the strut levers. v I

Figure 9 is a sideelcvation of one of the latches "For the joint between the opposed ends of the stringeror side board sections.

Myimproved piano-bench and cot conibination comprises with theparts set up for use as a piano-bench what appears to be a box-like structure, 10 that is set up on fragmentary plan view 'on' fouriegs 11 and is surmounted by a top'or cover 12 that servesas the seat proper, said seat 12 being connected tothe headboard la by means of suitable hinges .1 3.

Said box-like structure lOcomprises the legs 11 at'the corners, the head board 14 along one of the longer sides or sides proper the foot board 15 along the opposite side proper, and relatively shorter end or crossboards at the 'ends. Said end'boards comprise the endboard 16 at the rightside' and theend board 17 at the left side.

When used as acot, the cover 12is tilted back. I I The headboard 1 1 and the adjacent legs 11 are rigidly united as a fixed structure and one ofthe endboards is joined pernianently to said fixed structure so as to form in a unitary structure thestructure ofthehead end of the cot and a part one of the side stringers, constituting arightangled corner of said cot structure. As shown, the endboard 16 forms part of the corner 18 at the right side of the head end, being joined to the head end board 14 through the medium of the leg 11 that is intermediate these parts. l

Ina similar way at thefoot end of the cot the corner 19; diagonally opposite the corner .18, is composed or the foot hoard 15, the leg 11, and the end hoardll', said corner 19 being also a rigidstructure. 7

The corners of the bench i termediatethe corners 18 and 19 are broken, and the parts composing the same are united indirectly through the medium of collapsible devices to be described.

Thus considering the lelft hand corner 20 at; the head endfthe leg 11 at said corner constitutes the free end portion of" the head end structure 21 that is composed of the head'hoardls and the adjacent legs 11 free end .415 of the end board 17.

A hinge 26 serves to interconnect the other opposed ends oi said board sections 24.

Thus in the cot position, means are provided for a substantially straight stringer on the left side that is composed of the two board sections 2 1- that extend from the head end structure 21 towards the foot and that constitute the major portion of the length, and the end board 17 at the foot end.

In a similar way the corner 27 that is diagonally opposite the corner 20 is composed of the free end portion 28 of the right end board 16 in abutment with the opposed leg 11 at the right hand end portion of the foot board structure 29, and these parts are interconnected by a collapsible structure that is similar to that described with reference to the corner 20, the board sect-ions 24 and hinges 25 and 26 being similar.

The only difference between the two stringer or side board structures is that the end boards and collapsible structures are reversed in their relative positions, the end board 16 on the right side being at the head end and the collapsible structure at the right side is connected directly to the foot board structure 29. I

In the case of the section hinges 26, these are located on the outer faces of the sections 24 that are connected thereby when the device is in extended position, and I provide on the opposite inner face of each stringer structure a reinforcing latch 30 of strap iron that bridges the gap or junction at the abutting ends of the section boards 24.

and helps in holding the parts relatively rigid. i

The cot proper or supporting bed 31 is rigidly secured to the head end structure 21 in a proper manner, as by means of a metal strip or cleat 32 and suitable securing devices is provided with means for supporting the foot end portion that permit of readily connecting and disconnecting the parts, as will be described, and is made of a form that is adapted to be rolled up from the foot towards the head, as by the use of a cross-bar 33 at the foot as a core.

The bed 31 shown is made up as a spring bed or mattress of a plurality of sections of fabric that are interconnected by means of suitable sets of coil springs 34, and the crossbar 33 is housed in a hem or loop 35 in the foot end section 36. Said foot end section 36 is relatively short. The section 37 at the head end may, however be' still shorter, as shown. The third and interme diate section 38 is relatively long and extends the major portion of the length of the structure of the bed 81. I

For cooperating'with the hook ends 39 of the springs 34 there are provided in the fabric diminutive foldsor loops lO in which are housed in each case a cross-rod 41 of metal for distributing the strain. of: the springs. a

The foot cross-bar utilized for of; footing the connection for the bed 31 at the foot end by means of a laterally directed stud l2, which preferably is a headed stud, as shown, and which projects laterally from the end thereof, there being one such stud 42 at each end.

As a detail, the stud -12 is mounted on a metal bracket e8 that is secured in any proper manner on the cross-bar 33.

Also, said stud a2 is set in off-set relation to the center of said cross-bar 83, so as to be nearer to one of the side edges at than the other, as shown, s0 that the bar can be turned one way or the other to effect an appreciable change in the effective length of the cot or bed 31 and thereby can change the tension or stretch of the bed structure.

The stud 42 is adapted to make operative engagement with a suitable notch 45 in the upper edge portion of a suitable strip of iron that is in registration therewith, said strip, as shown, being in the form of a lever l6 that operates as a strut, being subject to compression when in position for use as well as transverse strain, and being pivotally supported for permitting of being shifted when the parts are brought to the closed position.

Thus the pivotal connection H for the lever to is provided at the head end on the inner face of the opposed board section 24 so that it is adapted to be swung either towards the foot end for the active position or towards the head end for the idle posi tion. In either case a post that serves as a stop is provided to limit the swinging movement and support the free end portion. Thus at the foot end is the inwardly directed stop 48, supported by the side stringer structure, and at the head end is the stop 49. I

The active stop 418 at the foot end is placed so that in assembling the stud 42 is brought below the line of centers as determined by the pivotal connection 47 and the two end supports for the bed 31, thus permitting the structure of the same being subjected to longitudinal tension when in the assembled position. This condition involves a tendency to hold the parts in the assembled relation and to resist any action that would have the effect of changing and disturbing such assembled relation.

1n the closed position the board sections 2d are folded together and the bed 31 is for the most part rolled up on the cross-bar 33, and these parts are housed within the box-like structure 10, there being ample room for receiving and entirely enclosing the same, so as to be invisible when the piano-bench is set up in the ordinary manner for use.

'I claim as my invention 1. A piano-bench and cot combination comprising in the closed position a box-like structure or rectangular form that is supported by a set of legs, said structure comprising extensions of said legs at the corners side boards extending along the longer sides, and end boards at the shorter sides, the side boards being connected by their ends with the opposed legs, the end boards being indi vidually connected by one end to diagonally disposed legs and having the free end opposed to the adjacent leg and separated, therefrom by a broken joint, said broken joints being bridged in each case by a collapsible side rail section, and said rail sections being each provided with a hinged strut for connection with a crossrail on a bed bottom.

2. In a piano-bench and cot combination, a collapsible frame structure and a filler in the form of a bed structure, one end of said filler being fixedly secured to said frame structure, the other end of said filler having a fold, a cross-bar positioned in said fold, and means for connecting the ends of said bar with said frame structure, and said bar being of rectangular form of crosssection and having the connecting means at the ends positioned eccentrically with reference to the axis of the bar.
